For more than 60 hours, three miners sat in a refuge chamber deep inside Newmont’s Red Chris mine, waiting as rescue crews worked through a debris pile stretching 20 to 30 metres. Their safe return on July 25, 2025, became the latest chapter in a long history of mine rescues—and it’s worth comparing how this operation stacked up against two of the most famous: the Beaconsfield collapse in Tasmania and the Chilean miner saga of 2010.

What happened at Red Chris mine?

Collapse and initial response

  • Two fall-of-ground incidents occurred in the access way to the underground work area on Tuesday morning, July 23 (Newmont, operator of Red Chris).
  • The trapped workers—Kevin Coumbs, Darien Maduke, and Jesse Chubaty—were contractors for Hy-Tech Drilling (Newmont).
  • The miners reached a refuge chamber underground and had consistent access to food, water, and ventilation (Newmont).
The upshot

The refuge chamber at Red Chris gave the three men a safe staging area, but the rescue team still had to clear a 20–30 metre debris pile to reach them—a delicate operation that stretched over two full days.

Rescue operation details

The implication: The 60-hour window contrasts sharply with both Beaconsfield (14 days) and Chile (69 days), but the geology and refuge strategy made the difference.

Are the BC miners rescued?

Confirmation of rescue

  • Newmont confirmed that the three trapped workers were safely brought to the surface at approximately 10:40 p.m. PST on July 25, 2025 (Newmont official news release).
  • The company said it worked with emergency response teams and specialist teams from nearby mine sites (Global News).

Condition of the miners

  • Newmont reported the workers were in good health and spirits after being rescued (Newmont).
  • Premier Eby added that two of the miners were from British Columbia and one from Ontario (Global News).
  • They were taken to hospital for medical evaluation following the rescue.

The catch: While immediate health looks good, the long-term psychological and physical effects of being trapped underground for two and a half days often take months to fully surface.

Who are the miners trapped in Red Chris mine?

Identities of the three miners

  • Newmont identified the three trapped miners as Kevin Coumbs, Darien Maduke, and Jesse Chubaty (Newmont).
  • The Vancouver Sun confirmed their names shortly after the rescue (Vancouver Sun, regional newspaper).

Background and roles

  • The workers were contractors for Hy-Tech Drilling, a drilling services company (Newmont).
  • They were experienced workers at the Red Chris copper-gold mine, which is operated by Newmont in northwestern British Columbia (CBC News coverage).
Why this matters

Contract workers make up a large share of the labour force in remote mining operations. Their training and refuge access were critical factors in this successful outcome.

The pattern: Clear identification and background information help build trust in the reporting.

What happened to Brant Webb and Todd Russell?

Beaconsfield mine collapse overview

  • On April 25, 2006, a small tremor caused a rock burst at the Beaconsfield gold mine in Tasmania, trapping Brant Webb and Todd Russell 925 metres underground (BBC News, international news organisation).
  • They were trapped in a steel “basket” cage for five days before rescuers realised they were alive (BBC News).

Their rescue and aftermath

  • Webb and Russell were rescued after 14 days, on May 9, 2006, after rescuers drilled a shaft through solid rock (Wikipedia, detailed mining incident reference).
  • Both survived; Todd Russell later became a public figure, running for political office in Tasmania (Wikipedia).

What this means: The Beaconsfield rescue took two weeks versus the 60-hour Red Chris operation—driven largely by the fact that the Tasmanian miners were initially thought dead and lacked a purpose-built refuge chamber.

Did all the 33 miners survive?

Chilean mine collapse of 2010

  • On August 5, 2010, the San Jose copper-gold mine near Copiapó, Chile, collapsed, trapping 33 miners 700 metres underground (The New York Times, major U.S. newspaper).
  • All 33 were found alive after 17 days, thanks to a small borehole that reached their shelter (BBC News).

Rescue and survival of all 33

  • The rescue operation lasted 69 days, ending on October 13, 2010, when the last miner was brought to the surface in a special capsule (The New York Times).
  • The event became a global media phenomenon, later depicted in the film The 33 (Wikipedia).
The trade-off

The Chilean miners had far more severe confinement and a longer rescue timeline, but they also had a larger team and a structured shelter with supplies that sustained them for 69 days. Red Chris miners had a shorter ordeal but faced faster-response emergency protocols.

The implication: Each rescue’s timeline reflects a unique combination of geology, infrastructure, and luck.

Three rescue operations, three different timelines, and one pattern: the speed of rescue often comes down to geology, refuge infrastructure, and whether the miners can be located quickly. Let’s compare the key differences side by side.

Factor Red Chris (2025) Beaconsfield (2006) Chile (2010)
Number trapped 3 2 33
Depth Unknown (refuge chamber approx. 20-30m debris) 925 m 700 m
Time underground 60+ hours (2.5 days) 14 days 69 days
Cause of entrapment Fall of ground (partial collapse) Rock burst (seismic event) Collapse of main access ramp
Refuge strategy Purpose-built refuge chamber with food/water/ventilation Steel cage with limited supplies Emergency shelter with food/water for days
Rescue method Protected equipment through debris Drilled shaft through rock Drilled borehole, then capsule hoist
Health outcome All good health Both survived All 33 survived

Timeline of the Red Chris mine rescue

  • – Partial collapse at Red Chris mine traps three workers underground (Newmont).
  • – Rescue operation begins; debris pile described as 20–30m long; authorities notified (Global News).
  • – All three miners safely brought to surface after more than 60 hours (Newmont).
  • – Miners taken to hospital; reported in good health (Canadian Occupational Safety).

Clarity check: What we know and what remains unclear

Confirmed facts

What’s unclear

  • Exact cause of the collapse
  • Whether the mine will remain closed for investigation
  • Long-term health impact on the miners
  • Specific rescue technique used to reach the refuge chamber

“The workers were safely brought to the surface at approximately 10:40 p.m. PST on July 25, 2025.”

— Newmont, the mine operator, in a statement (source)

“The miners are in a refuge area and are not injured.”

— BC Premier David Eby (Global News quoting Premier Eby)

For Newmont, the safe rescue is a relief, but the full investigation will determine whether operations resume—or if the incident becomes a turning point for underground safety protocols in British Columbia. For the families of the three miners, the 60-hour wait is over, but the memories of those hours underground will not fade quickly. The comparison with Beaconsfield and Chile shows that every minute counts, and a well-equipped refuge chamber can make the difference between a two-day rescue and a two-week ordeal.

Bottom line: The Red Chris mine rescue succeeded because the three miners had a refuge chamber with supplies and the rescue team acted swiftly. Newmont: invest further in refuge infrastructure. BC regulators: use this incident to benchmark emergency response times across the province’s remote mining operations.

Frequently asked questions

What is the Red Chris mine?

The Red Chris mine is a copper-gold mine located in northwestern British Columbia, about 500 km northwest of Terrace. It is operated by Newmont, one of the world’s largest gold mining companies.

Who operates the Red Chris mine?

Newmont is the majority owner and operator of the Red Chris mine, a joint venture with other partners.

What caused the collapse at Red Chris mine?

Two fall-of-ground incidents in the access way caused the partial collapse. The exact cause remains under investigation by Newmont and BC authorities.

Has the Red Chris mine reopened after the rescue?

No. Newmont has paused underground operations pending a full investigation. A geotechnical inspector has been dispatched to the site.

What safety measures were in place at Red Chris mine?

The mine had refuge chambers with food, water, and ventilation, and the rescue team used protected equipment to reach the trapped workers.

How did the rescue operation work?

Teams from the mine site and nearby operations cleared a 20–30 metre debris pile to reach the refuge chamber. The miners were then brought to the surface using the same protected equipment.

Were there any injuries during the rescue?

No rescue team members or miners were injured. All three trapped workers were reported in good health.
